Description

Technical Field

[0001] The embodiments of this application relate to the field of cosmetic packaging technology, and in particular to a packaging container. Background Technology

[0002] This section is only intended to provide background information relevant to this application and does not necessarily constitute prior art.

[0003] Currently, some cosmetic packaging containers are made of highly transparent, thick-walled materials to enhance the product's texture and aesthetics. For these types of containers, a pump head is typically required to dispense the liquid, or a brush is used for application.

[0004] However, these types of packaging containers still have many limitations. Utility Model Content

[0005] A brief overview of this application is provided below to offer a basic understanding of certain aspects thereof. It should be understood that this overview is not an exhaustive summary of the application. It is not intended to identify key or essential parts of the application, nor is it intended to limit its scope. Its purpose is merely to present certain concepts in a simplified form as a prelude to the more detailed description that follows.

[0006] Embodiments of this application provide a packaging container, comprising: an outer bottle, a cap, and a flexible inner bottle. The top of the outer bottle forms an outer bottle opening for discharging material, and the bottom of the outer bottle forms an opening. The cap is used to open or close the outer bottle opening. The flexible inner bottle is used to contain liquid material and is detachably connected to the outer bottle through the opening. The flexible inner bottle is configured to deform under pressure so that the liquid material therein is squeezed out from the outer bottle opening.

[0007] The packaging container provided in the embodiments of this application allows users to control the dispensing of liquid by pressing the flexible inner bottle. Since the flexible inner bottle and the outer bottle are detachable, when the liquid in the flexible inner bottle is used up or when the user wants to use multiple types of liquid, they only need to purchase the liquid packaged in the flexible inner bottle and replace the flexible inner bottle of the packaging container, without having to repurchase the liquid packaged in the entire packaging container, thereby saving materials and minimizing waste.

[0008] Furthermore, the outer bottle may include: an outer bottle body and an outer shoulder for connecting the outer bottle opening and the outer bottle body; wherein, an opening is formed at the bottom of the outer bottle body.

[0009] Furthermore, the flexible inner bottle may include: an inner bottle body, an inner bottle opening, and an inner shoulder for connecting the inner bottle opening and the inner bottle body; wherein the inner bottle opening and the outer bottle opening are detachably connected.

[0010] Furthermore, an external thread is formed on the radially outer surface of the inner bottle opening, and an internal thread is formed on the radially inner surface of the outer bottle opening accordingly, so that the inner bottle opening and the outer bottle opening are threadedly connected.

[0011] Furthermore, the inner part of the outer bottle opening is formed with a first channel, a second channel, and a third channel from top to bottom; the inner diameter of the first channel is smaller than the inner diameter of the second channel, the inner diameter of the second channel is smaller than the inner diameter of the third channel, and the inner wall of the third channel is formed with internal threads; the inner bottle opening includes, from top to bottom, a liquid outlet section and a connecting section, with external threads formed on the connecting section, and the liquid outlet section conforming to the shape of the second channel.

[0012] Furthermore, the second channel is higher than the liquid outlet section, and the liquid flowing out of the liquid outlet section enters the second channel and then enters the first channel.

[0013] Furthermore, the inner diameter of the second channel gradually decreases in the direction away from the third channel.

[0014] Furthermore, the inner diameter of the first channel gradually decreases in the direction away from the second channel.

[0015] Furthermore, the inner bottle body may include a first inner bottle segment and a second inner bottle segment connected to the first inner bottle segment, the first inner bottle segment being located radially inside the outer bottle body, and the second inner bottle segment being located below the outer bottle body.

[0016] Furthermore, the radial outer surface of the second inner bottle segment is basically flush with the outer bottle body.

[0022] Exemplary embodiments of this application will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as meeting constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from the content of this application.

[0023] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the equipment structure and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0024] It should be noted that, unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning as understood by a person with ordinary skills in the field to which this application pertains.

[0025] In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] For packaging containers made of highly transparent, thick-walled materials, once the liquid is used up, the entire container is discarded. This not only wastes materials but also pollutes the environment, which is very detrimental to environmental protection.

[0027] Based on this, embodiments of this application provide a packaging container.

[0028] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a packaging container according to an embodiment of this application. Figure 2 yes Figure 1 The diagram shows a cross-sectional view of the packaging container along the AA direction. The packaging container may include: an outer bottle 1, a cap 2, and a flexible inner bottle 3. The top of the outer bottle 1 forms an outer bottle opening 11 for discharging material, and the bottom of the outer bottle 1 forms an opening 10. The cap 2 is used to open or close the outer bottle opening 11. The flexible inner bottle 3 is used to contain the liquid material. The flexible inner bottle 3 enters the outer bottle 1 through the opening 10 and is detachably connected to the outer bottle 1. The flexible inner bottle 3 is configured to deform under pressure so that the liquid material inside is squeezed out from the outer bottle opening 11.

[0029] The packaging container provided in the embodiments of this application has an opening 10 at the bottom of the outer bottle 1 and a flexible inner bottle 3 that is detachably connected to the outer bottle 1 and enters through the opening 10. This allows the user to squeeze out the liquid by pressing the flexible inner bottle 3. Since the flexible inner bottle 3 is detachable from the outer bottle 1, when the liquid in the flexible inner bottle 3 is used up or the user wants to use multiple types of liquid, they only need to purchase the liquid packaged in the flexible inner bottle 3 and replace the flexible inner bottle 3 of the packaging container, without having to repurchase the liquid packaged in the entire packaging container. This saves materials and minimizes waste.

[0030] Because the liquid packaged in the flexible inner bottle 3 can be different types of cosmetic liquids (such as blush liquids or foundation liquids of different shades), it can also maximize the reuse of packaging containers while meeting the diverse needs of users.

[0031] In some embodiments, the flexible inner bottle 3 may be made of PE material to meet the requirement of softness, thereby facilitating pressing.

[0032] In some embodiments, both the outer bottle 1 and the bottle cap 2 can be made of PETG material, which satisfies the requirements of high transparency and high thickness while also being aesthetically pleasing.

[0033] In some embodiments, the outer bottle opening 11 may be formed with an external thread, and the bottle cap 2 may be formed with an internal thread, and the bottle cap 2 is threadedly connected to the outer bottle opening 11.

[0034] In some embodiments, see Figure 3 and Figure 4The outer bottle 1 may further include: an outer bottle body 12 and an outer shoulder 13 for connecting the outer bottle opening 11 and the outer bottle body 12; wherein, an opening 10 is formed at the bottom of the outer bottle body 12. The outer shoulder 13 helps to reduce the inner diameter of the outer bottle opening 11, making it easier to control the liquid output.

[0035] In some embodiments, see Figure 5 and Figure 6 The flexible inner bottle 3 may include: an inner bottle body 31, an inner bottle opening 32, and an inner shoulder 33 for connecting the inner bottle opening 32 and the inner bottle body 31; wherein the inner bottle opening 32 is detachably connected to the outer bottle opening 11.

[0036] In this embodiment, the inner bottle opening 32 and the outer bottle opening 11 are detachably connected, enabling the assembly and separation of the outer bottle 1 and the flexible inner bottle 3. Furthermore, the inner bottle opening 32 directly connects to the outer bottle opening 11, ensuring that the liquid can directly enter the outer bottle opening 11 from the inner bottle opening 32 when pressed, thereby preventing leakage. The inner shoulder 33 facilitates a smoother flow of liquid from the larger inner bottle body 31 to the narrower inner bottle opening 32, while also preventing liquid stagnation.

[0037] In some embodiments, the outer shoulder 13 and the inner shoulder 33 are adapted in shape. Both the outer shoulder 13 and the inner shoulder 33 can be inclined conical surfaces.

[0038] In some embodiments, an external thread 321 is formed on the radially outer surface of the inner bottle opening 32, and an internal thread is correspondingly formed on the radially inner surface of the outer bottle opening 11, so that the inner bottle opening 32 and the outer bottle opening 11 are threadedly connected. In such an embodiment, the threaded connection between the inner bottle opening 32 and the outer bottle opening 11 can prevent the flexible inner bottle 3 entering the outer bottle 1 from falling out of the bottom opening 10 of the outer bottle 1, thereby enhancing the stability of the flexible inner bottle 3 after being connected to the outer bottle 1; at the same time, the threaded connection between the inner bottle opening 32 and the outer bottle opening 11 facilitates the disassembly of the flexible inner bottle 3 and also helps to prevent liquid from entering the outside of the inner bottle opening 32.

[0039] In some embodiments, see Figure 2 and Figure 4 The inner surface of the outer bottle opening 11 contains, from top to bottom, a first channel 110, a second channel 111, and a third channel 112. The inner diameter of the first channel 110 is smaller than that of the second channel 111, the inner diameter of the second channel 111 is smaller than that of the third channel 112, and the inner wall of the third channel 112 is formed with internal threads. See also... Figure 2 and Figure 5 The inner bottle opening 32 includes, from top to bottom, a liquid outlet section 322 and a connecting section 323. An external thread 321 is formed on the connecting section 323. The liquid outlet section 322 is conformally matched with the second channel 111.

[0040] In this embodiment, an internal thread is formed on the inner wall of the third channel 112 to match the external thread 321 formed by the connecting section 323, thereby connecting the outer bottle 1 and the flexible inner bottle 3 by threads, preventing displacement or shaking when the flexible inner bottle 3 is pressed; since the inner diameter of the channel gradually decreases as it gets closer to the liquid outlet, the liquid can be more concentrated and excessive liquid flow can be avoided due to an excessively large inner diameter, which is conducive to better control of the discharge amount; since the liquid outlet section 322 is conformally matched with the second channel 111, the liquid outlet section 322 and the second channel 111 are tightly fitted, thereby preventing the liquid flowing into the second channel 111 from leaking from the radial outer side of the liquid outlet section 322.

[0041] In some embodiments, see Figure 2 The second channel 111 is higher than the outlet section 322. The liquid flowing out of the outlet section 322 enters the second channel 111 and then enters the first channel 110. In this embodiment, by setting the second channel 111 to be higher than the outlet section 322, the liquid flowing out of the outlet section 322 enters the second channel 111 first, which can form a buffer and avoid excessive or too fast discharge due to uneven pressing pressure.

[0042] In some embodiments, see Figure 4 The inner diameter of the second channel 111 gradually decreases in the direction away from the third channel 112; the inner diameter of the first channel 110 gradually decreases in the direction away from the second channel 111. In this embodiment, by gradually reducing the inner diameter of the second channel 111 and the inner diameter of the first channel 110, the liquid output can be more concentrated, while avoiding excessive liquid output due to excessively large channel inner diameters.

[0043] In some embodiments, the height of the first channel 110 is higher than the height of the second channel 111 and higher than the height of the third channel 112, so that the first channel 110 is long and narrow, which facilitates smooth material discharge.

[0044] In some embodiments, see Figure 5 and Figure 6 The inner bottle body 31 may include a first inner bottle segment 311 and a second inner bottle segment 312 connected to the first inner bottle segment 311. The first inner bottle segment 311 is located radially inside the outer bottle body 12, and the second inner bottle segment 312 is located below the outer bottle body 12. In this embodiment, by placing the second inner bottle segment 312 below the outer bottle body 12, the user can control the flow of liquid by pressing the second inner bottle segment 312, which improves the convenience of operation and thus enhances the user experience.

[0045] In some embodiments, see Figure 2 and Figure 6The second inner bottle segment 312 and the first inner bottle segment 311 form a stepped surface 3121, and the outer bottle body 12 abuts against the stepped surface 3121, which can restrict the axial movement of the inner bottle body 31, thereby further improving the stability of the inner bottle body 31.

[0046] In some embodiments, the radial outer surface of the second inner bottle segment 312 is substantially flush with the outer bottle body 12, so that the overall outline of the packaging container is regular and uniform and the appearance is neater and more beautiful, which helps to improve the refinement of the packaging container and thus improve the user experience.

[0047] After the liquid inside the flexible inner bottle 3 is used up, the flexible inner bottle 3 can be separated from the outer bottle 1 and a new flexible inner bottle 3 containing liquid can be replaced to reuse the outer bottle 1 and the cap 2.

[0048] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0049] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. The scope of protection of this application shall be determined by the scope of the claims.
